Pregnant Kristin Cavallari Drinks 'MockTails' for her Birthday: 'Enjoying a mock-tail for the big 2-7!'

Kristin Cavallari was known as the girl who loves cocktails on the TV show The Hills but times have changed as she's now a wife and mother. She's pregnant with her second child. When she celebrated her 27^th birthday on Sunday, Jan. 5, instead of a cocktail, she had mocktails!

She shared an Instagram photo on Sunday where she was with her husband Jay Cutler, with the caption: "Thank u for all the birthday love. Enjoying a "mock-tail" for the big 2-7!"

The Laguna Beach star was dressed in a black top which showed her growing baby bump. Her hair was worn down and had heavy eyeliner. Her husband looked handsome in a grey blazer with a button-down shirt. The couple appeared to be enjoying dinner at a restaurant.

In October, the couple announced they were expecting another child. The two are already parents to 1-year-old son Camden Jack.

They have not revealed if the baby's a boy or a girl but she recently told E! News, "There's great things about both. Another boy would be fun: Cam would have a little buddy and then I'd be the woman of the house."

"But of course I want a little girl, so I don't know. Either one would be great."

Aside from the exciting baby news, the family has received even more good news as Cutler re-signed a seven-year contract with the Bears, which is reportedly worth more than $100M.

The two have started dating in 2010 and were engaged in 2011. They were married since June 2013.
